Natural selection is part of Darwin's theory of evolution saying that those individuals within a species that don't adapt well to their environment will eventually die off, while those that do adapt will continue on with future generations.
Facts About Darwin's Research
- Recently graduated from college, Darwin joined up with a British Navy mapping ship that was going on an expedition around the world.
- Darwin wasn’t the first scientist to study the idea of evolution; however, he was the first to come up with a workable theory about how, exactly, this evolution took place.
- Darwin's research focused on:
- The adaptation of a species in order to survive in various conditions
- The variation among individuals that caused them to live while others died
- The passing on of those advantageous traits
An example of natural selection are insects which are resistant to pesticides.
- (evolutionary biology) A process by which heritable traits conferring survival and reproductive advantage to individuals, or related individuals, tend to be passed on to succeeding generations and become more frequent in a population, whereas other less favourable traits tend to become eliminated.
- (quantitative genetics) A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.
